Trimethylsilanol (Hydroxytrimethylsilane) (CAS: 1066-40-6) is an organosilicon derivative of silane used as a hydrophobic coat on silicate surfaces. The surface produced by Trimethylhydroxysilane is composed of methyl groups.
Used as End-Capping Agent. Trimethylsilanol is one of the common silanols, which can be used as the end-capping agent of linear polysiloxane to introduce hydroxyl groups into linear polysiloxane.
